MARQUIE DATA SYSTEMS

Databases · Reliability · Modernization

Database reliability and modernization for business-critical systems.

We stabilize, modernize, and operate SQL Server, MySQL, PostgreSQL, and cloud database platforms — along with the reporting, automation, and operational workflows that depend on them.

Engagements address difficult migrations, availability failures, performance bottlenecks, fragile reporting, and recurring manual work. Each is led by a senior database practitioner with decades of production experience.

No unnecessary platform replacement. No vague scope. The work, controls, and acceptance criteria are defined before execution.

Or browse the free SQL Server tools hub — wait stats, blocking chains, deadlocks, missing indexes, backup RTO/RPO, and a health-score card. No email required.

Three practices

Every engagement fits one of these. Scoped in writing, delivered by the practitioner who did the assessment.

Database reliability

Performance, availability, backup and recovery, security, and operational job health for production database systems.

How we scope it →

Modernization & migration

Controlled platform moves — cross-platform conversion, cloud migration, dependency discovery, parity validation, and cutover planning with rollback preserved.

How we scope it →

Reporting & data automation

Reporting, data movement, and recurring operational workflows — with governed automation and AI applied where it produces a measurable benefit.

Productized engagements

Fixed-scope entry points. Fees are quoted in writing after a 30-minute scoping call; the Health Check Lite starts at $1,500.

Plus an ongoing DBA retainer that pairs with any of the engagements above — a senior DBA on call without a full-time hire.

Who we work with

Local businesses

Restaurants, garages, dental offices, contractors, and retailers where the same manual steps show up every week — and the systems underneath (QuickBooks, POS, scheduling) need to stay fast and backed up. The Health Check Lite is still the door — starting at $1,500, one week — or start with the free self-assessment.

Based in Ossining, NY — serving Westchester and the lower Hudson Valley: Briarcliff Manor, Croton-on-Hudson, Sleepy Hollow, Tarrytown, Pleasantville, Chappaqua, Yorktown Heights.

Mid-market operators

Teams where slow reports, fragile pipelines, or downtime cost real money. We bring senior DBA depth to the production databases you already run — with compliance-aware practice (SOC 2, PCI DSS, SOX) when audits matter. See how these engagements run.

Remote, anywhere in the U.S.

Alongside the database practice we take on a focused set of remote, fixed-fee growth projects — customer reactivation, review sentiment, loyalty, vendor and COGS tracking — built from data you already collect.
